There is a simple method that Andres Moritz spoke of where you dissolve inert charcoal into the olive oil and watch it turn black. You then do the flush with this oil which is totally harmless. The black substrate comes out however with the green and calcified stones, hence showing that the olive oil is not forming the stones or alternatively you can have them tested if you are still a little unsure. I have been in a very similar situation to you as I liked my Sugar and parties. Eventually liver kicked in. I have been years trying to regain full health and about 13 flushes later I am starting to feel allot better. I think the missing link for me was solving why the stones were forming in the first place. Repressed anger seems to have been the culprit and with the use of (EFT) Tapping I am now well on my way to full health. Peace brother.
